FREDERICK H. PERRY, OF BEVERLY, MASSACHUSETTS, ASSIGNOR TO UNITED SHOEMACHINERY CORPORATION, OF PATTERSON, NEW JERSEY, A CORPORATION OF NEWJERSEY.

SOLE-FITTING MAGHINE.

To all whom it may concern:

Be it known that I, FREDERICK H. PERRY, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Sole-FittingMachines; and I do hereby declare the following to be a full, clear andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to machines for use in the manufacture of bootsand shoes and more particularly to such machines for op erating upon themarginal portions of soles provided with a marginal lip which mayinclude a reinforcing layer of fabric.

There are several operations performed on the marginal portion of achanneled insole in preparing it for the subsequent welt sewingoperation. These include forming or molding the lip to a proper shape tobe acted upon by the welt sewing instrumentalities and, on the Economytype of reinforced insoles. trimming the canvas proiecting above the topedge of the lip. These operations are well known in the art of shoemaking and various machines have been devised for performing them.

The object of the present invention is to improve and simplify theconstruction and mode of operation of machines of the characterdescribed. To the accomplishment of this object. and such others as mayhereinafter appear, the invention comprises the features andcombinations of parts which are hereinafter described and particularlypointed out in the appended claims.

The preferred form of the invention is illustrated in the accompanyingdrawings, in which,

Figure 1 is a side elevation of the machine;

Fig. 2 is a longitudinal section of certain parts of the machine lookingin the opposite direction from Fig. 1;

Fig. 3 is a section on the line 3-3 of Fig. 1; I

Fig. 4 is a section on the line 4.4 of Fig. 2; and

Fig. 5 is a detail plan of the work engaging tools.

In the illustrated embodiment of the invention the sole to be operatedupon is sunported by a work table 10 which coacts with Specification ofLetters Patent.

Serial No. 215,157.

a feed wheel 12 to grip the feather and feed the work to the tools. Thework table and feed wheel are connected for rotation by gears 14 and 16mounted on separate vertically arranged shafts. The feed wheel is drivenby a worm gear 18 which meshes with a worm 20 on a driving shaft 22which may be driven by any suitable pulley connections (not shown). Theshaft 22 also carries an eccentric 24 which acts through a block 26 toreciprocate a fork 28 pivotally mounted on a stud 30 in the machineframe. The fork is provided with an integral arm 32 which actuates thelip hammer 3 to impart a succession of blows to the outside of the lipas the insole is fed past the hammer. In so far as has been described,the construction of the machine may be and preftrably is identical withthat shown in the United States patent to Hadaway No. 638,010., grantedNovember 28, 1899.

In the present machine the inside lip supporting tool or anvil 36 (Fig.2), against which the hammer compresses and molds the lip, is formed. onthe lower end of a rod 38 which is rigidly secured, by a nut 40 in abracket 42. The bracket is held in adjusted position on a casting 4:4-by a clamp screw 50 and. a. set screw 52 by which longitudinal andvertical adjustment of the anvil may be obtained. The casting 4411s, ineffect a part of the machine frame d6, it being secured thereto byscrews 48 (dotted lines in Fig. 2).

Provision is made for imparting a yielding blow to the hammer in orderthat the compression of the lip may not be so great as'to injure it,particularly when a thick portion of the lip is encountered. To this endthe connection between the hammer operating arm 32 and the hammer 34comprises a stud 54: (Figs. 2 andd) fixed in the arm and passing througha slot 56 in one end of a link 58. the other end of which is pivotallyconnected by a pin 62 with the hammer carrying slide 60. The ends of thelinks are slotted so as to embrace the ends of a spring 6 one end ofwhich bears against the stud 54 and the other against the end of theslide 60. The hammer 34: is fastened to theslide by a screw 61. By thisconstruction the hammer is normally held in advanced position withrelation to thearm 32. but when the hammer has compressed the lip withsufiicient force to overcome the spring 64',

the slot 56' permits the arm to complete its normal movement withoutexerting undue, pressure on the work.

The canvas or other reinforcing material is trimmed to a uniform heightabove the sole by a reciprocating knife 66 which 1s located above thehammer 34 and cooperates with the anvil 36 to produce a shearing cut.The anvil 36 is preferably made in two parts, the upper part consistingof a hardened steel washer or shearing disk 68 which is clamped betweenthe lower part 36 and the bracket 42 by the nut 40. When the portion ofthe disk in operative relation with the knife 66 has become dull, thenut 40 may be loosened and the disk may be partially rotated to presenta new portion of the edge to the knife. hen the entire upper peripheryhas been used. the disk may be reversed so as to use the opposite sideas a shearing surface. This construction avoids the necessity ofsharpening the shearing edgeof the anvil, as dull disks may be discardedand new ones substituted without disturbing the adjusted position of theanvil.

If the leather lip has not been trimmed previously it also may betrimmed by the knife 66. The shank of the knife is offset (see Fig. 5)and is clamped in a dovetailed slot in the forward endof a slide 70(Fig. 1) by a screw 72 which permits adjustment of the knife toward andfrom the anvil 36. The slide 76 is mounted in a way having the usual!gib 74 in an adjustable knife carrier 76- (Figs 1 and 3). The rear endof the slide 70' is slotted in one face to embrace a bloolt 78 looselymounted on a pin 80 projecting from the arm 32. By this construc tionthe hammer 34' and the knife 66 are actuated simultaneously by theeccentric 24, but whil'e the knife has a positive reciprocation, thehammer has a variable movement because of the yielding connectionheretofore described.

lmife carrier 76 is pivotally mounted in the frame 48- by a stud 82,about which it may adjusted to raise or lower the knife by themanipulation of screws 84 1) threaded through a ledge 86 projecting fromthe casting 44-. To obtain a clean severance of the canvas, the verticalrelation between the knife 66 and the upper surfaee' 68 of the anvilmust be accurate. The anvil must also be cap'abie of adjustment andconvenient to remove to substitute others' 'toaccommodate differentclasses of work. The construction described permits convenientadjustment of both these pbrtsso that a clean out will always beobtained'.

. While the various features of the prefer-red form of the inventionhave been described as applied toa machine for operatmg upon reinforcedinsoles of the Economy t pe, it will be apparent to those skilled in tieart that certain features of the invention may advantageously beemployed for operating upon reinforced insoles of other types, or uponall leather insoles.
